81208 -TV INA cylindrical roller thrust bearing

INA 81208-TV Cylindrical Roller Thrust Bearing (Polyamide Cage)

The INA 81208-TV is a high-precision thrust bearing designed to accommodate heavy axial loads acting in a single direction. The unit consists of a cylindrical roller and cage assembly along with two washers: the shaft washer and the housing washer. The standout feature of this model is the glass-fiber reinforced polyamide 66 cage (TV). This design ensures excellent roller guidance, reduces the overall bearing weight, and provides significantly quieter operation, which is critical for modern high-speed drive systems.

Application

• Machine Engineering: Machine tool spindles, rotary tables, and high-pressure screw actuators.
• Automotive: Power transmission systems, gearboxes, and high-pressure pump components.
• Automation & Robotics: Axial support in industrial manipulators and slewing units.
• Energy Sector: Bearing support for rotors in vertical generators and pumps.
• Mechanical Construction: Industrial presses and lifting equipment.

Technical Specification

• Manufacturer: INA (Schaeffler Group - Germany).
• Designation: 81208-TV.
• Dimensions: 40 mm (ID) × 68 mm (OD) × 19 mm (Total height).
• Cage Type: TV – Glass-fiber reinforced Polyamide 66.
• Load Type: Unidirectional axial loads only.
• Design: Separable (facilitates independent mounting of components).

Features and Benefits

• Extreme Axial Rigidity: Cylindrical geometry provides a linear contact surface, minimizing deflection under load.
• Optimized TV Cage: The polyamide design reduces friction, prevents overheating, and lowers noise emissions.
• Ease of Installation: Separate washers and roller assemblies significantly shorten assembly time.
• High Efficiency: Precision-ground raceways lead to lower energy consumption for the equipment.
• SCHAEFFLER Quality: Premium product ensuring long service life and exceptional reliability.

Why Choose This Product

By choosing the INA 81208-TV bearing, you are investing in a product from the industry leader, the Schaeffler Group. Thanks to the modern polyamide cage, this bearing handles dynamic speed changes more effectively and offers higher mechanical efficiency than versions with metal cages. It is a reliable solution that protects your machinery from premature wear and ensures stable operation even under extreme axial pressure.
